FILTER.

Application filed April 10, 1922.

To aZZ whom it may concern:

Be it known that I, CLARENCE F. HnYsnR,

a citizen of the United States, residing at Battle Creek, in the county of Calhoun and State of Michigan, have invented new and useful Improvements in Filters, of whlch the following is a specification.

This invention relates to filters, and has particular application to a funnel attachment for this purpose, the attachment being very simple in construction, and capable of being easily and quickly associated with or detached from the funnel as the occaslon requires.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawing, the invention residing in the construction, combination, and arrangement of parts as claimed.

In the drawing forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is a side elevation, partly in section of a funnel showing the attachment associated therewith.

Figure 2 is a plan view of the perforated plate.

Referring to the drawing in detall, 10 111- dicates a tunnel of wellknown construction, the neck of which is of uniform diameter. The neck terminates to provide an annular bead 11, upon which the attachment is supported. The attachment consists of a plate or disk-like member 12 which is arranged immediately beneath the neck of the funnel and has its edge slightly curved to partly embrace the head 11. The plate or disk 12 is perforated as at 13, while interposed between this plate and the neck of the funnel is a layer of cotton, felt or any other material Suitable for use as a strainer, this ma- Serial No. 551,092.

terial being indicated at 14. The disk or plate 12 is formed with spaced lugs 15 which are curved to overlie the bead 11, while projecting from the disk or plate 12 is an apertured lug 16, which supports a threaded adjusting element or screw 17. Manifestly, when the screw is tightened into contact with the bead, it cooperates with the lugs 15 to hold the plate or disk 12 associated with the funnel in the manner illustrated in Figure 1.

While it is believed that from the foregoing description the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

hat I claim is The combination with a funnel having a neck portion, the lower edge of which is rounded to form a head, of a filter for said funnel including a disk like member arranged directly beneath the neck of the funnel and perforated, the outer edge of said disk being curved to partly embrace the bead of the neck, higs projecting from the curved edge of said disk at spaced points and curved to overlie said bead of the neck to assist in holding the filter associated with the tunnel, a filtering element arranged be tween the neck of the funnel and said disk, an additional lug rising from the edge of said. disk and lying in a plane between the first mentioned lugs and wholly above the head of said neck, and a threaded element carried by the last mentioned lug and arranged to engage the neck of the funnel to hold the filtering device associated with said neck.

In testimony whereof I affix my signature.

CLARENCE F. HEYSER.
